We are expecting DC3 and are looking into car seat options. We have a 7yr Old and a 4yr Old. Having spoken to the advisors at one store, we understand we could legally and safely have a rear facing car seat for the baby, a high backed booster for the 4yo and the 7yo in the middle between them on a little booster. But we’re worried she’ll be a bit squished. We have a Vauxhall Insignia. Someone recommended a MultiMac to us (multimac.co.uk/what_it_is) but it’s very pricey. We think we could just about stretch to it if we compromise on other things. Does anyone have one? Is it worth the money?!
